  ! Moyenne - a des frequences differentes - des valeurs bien definies
  ! (.NE.missing_val) des variables interpolees a un niveau de
  ! pression.
  ! 1) les variables de type "day" (nout=1) ou "mth" (nout=2) sont sommees
  ! tous les pas de temps de la physique

  ! 2) les variables de type "NMC" (nout=3) sont calculees a partir
  ! des valeurs instantannees toutes les 6 heures


  ! NB: mettre "inst(X)" dans le write_hist*NMC.h !
